COMBINED CHURN AND BUTTER-WORKER.

To all whom t may concern:

Be it known that we, AMANDA B. MC- LAUGHLIN and WILLIAM R. NrooLL, both citizens of the United States, residing at 0watonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in a Combined Churn and Butter-l/Vorker, of which the following is a specification.

This invention relates to a device for churning and for working the butter after it is churned, and the principal object of the invention is to provide a new and improved construction, combination and arrangement of parts for handling a small quantity of butter or the maximum quantity with equal ease and success. A further object of the invention is to provide a construction of this class in which mottles or streaks are kept out of the butter, but permitting the thorough incorporation of salt and moisture therein. Another object of the invention is to provide a construction in which the butter is more easily removed from the device.

Referring now more particularly to the drawing- Figure 1 is a side elevation showing the general construction of a device constructed in accordance with the principle of this invention; Fig. 2 is a sectional view showing the interior construction when the receptacle is at rest; and Fig. 3 is another view of the receptacle in a substantially opposite position to that shown in Fig. 2.

Combined churns and butter workers which have anv internal butter-working roller rotatable in the same or opposite direction to that of the drum itself, are well known in this art, and the present invention relates more particularly to the exact construction and location of the parts within the drum. Although a drum, circular in cross-section is shown, it is obvious that this invention is also applicable to a drum or receptacle which is not cylindrical.

In this invention, a drum 1 is supported by bearing standards 2 at its ends to rotate about a horizontal axis, the drum being commonly driven by a geared spider 3 attached to one end of the drum which meshes with a pinion Ll, carried by a driving shaft 5, upon which a driving pulley 6 is mounted. This shaft 5 also carries a gear 7 connected by means of a chain 8, with a gear 9, which Specification of Letters Patent.

Application led August 7, 1916. Serial No. 113,461.

is mounted on a shaft 10, connected to a butter-working roller 11, as shown in Fig. 2. This butter-working roller 11 is mounted at the center of the drum and rotates in the direction opposite to the direction of rotation of the drum, as indicated by the arrows in Fig. 2, but upon the same axis as the drum. rlhe drum is provided with a door 12, having hinges 13 at one side for pivotally mounting it, and a latch 14 at the other side for holding it closed. 1Within the drum are flights 15 and 16 spaced apart, and from one edge of the door opening and substantially opposite these flights are brackets 17, only one of which is shown, secured to the inside ends ofthe drum. These carry a rigid shelf 18 which extends from a point adjacent the inner periphery of the drum to the inner ends of the brackets 17 leaving a small space 19 between the outer end of the shelf and the inner surface of the vdrum for the passage of liquid, but not sufficient for the passage of any substantial amount of a semi-solid. At the inner ends of the brackets an idle roller 2() is mounted, which is therefore adjacent the butter-working roller 11. This completes the interior construction of the drum, but does not accurately define the exact location and angular arrangement of the parts.

At one end of the drum, on the outside thereof, is a pair of cleats 21 which form a notch for the engagement of an arm 22 pivoted to one of the bearing standards 2. These cleats are in such a position that when the drum is held stationary with the arm 22 in engagement with the notch formed by the cleats, the lower edge of the door opening is at a specific angle above the horizontal, as indicated by the letter a; in Fig. 2^ At this angle the drum and the door opening are most freely accessible to a person standing vat the adjacent side of the drum, and the angle which has been found to give the best satisfaction is approximately an angle of 22 degrees. When the door opening is in this position, the shelf 18 should be inclined slightly from the outer edge to the inner edge thereof, and this angle, indicated by the letter b, is about 8 degrees. With the shelf at this angle, the niassof butter would be partially confined by the roller 11, the shelf 18 and its roller 20, and the adjacent wall-of the drum directly below the door opening where it is fastened freely accessible. In this position the shelf is at suiiicient inclination to drain liquid therefrom toward the inner edge of the shelf. Tt is necessary also to define the axis of the idle roller 20, which is parallel to the axis of the butter-working roller 11, and substantially half Vthe distance between the inner side of the drum and the axis thereof, leaving a suflicient space between the butter-working roller 11 and the idle roller 20, the axis of the roller 2O also being at an angle c on that side of the vertical line adjacent the shelf, the angle being approximately 17 degrees.

This construction leaves the maximum possible space between the butter-working roller 11 and the fiights 15 and 16 when the device is in operation, as shown by Fig. 8, so there is the least danger of the butter being whipped by the roller 11 when the receptacle is in the position shown by F ig. 3. Then too with this construction, the device is in effect a two-roll butter worker, for the butter-working roller 11 presses the butter against the idle roller 2() when the drum is approximately in the position shown by Fig. 2, thereby rolling or kneading the butter instead of cutting it as is the case when the butter is worked directly from the shelf, or when the shelf consists of a number of slats instead of a solid piece. By running the roller 11 at a sufficient speed, the maximum quantity of butter is carried down between the two rollers 11 and 20, thus eliminating all possibility of mottles, streaks or uneven colors in the butter. This of course permits a thorough incorporation of salt and moisture in the butter. 1f the butter-working roller 11 is not in the center of the drum, and if it is nearer the flights 15 and 16, it is true that a greater quantity could be contained between the roller 11, the shelf 18 and the adjacent side of the receptacle below the door 12, but this would leave less space between the butter-working roller 11 and the fiights 15 and 1G, which would prevent the maximum quantity of butter from being evenly worked, as before set forth.

The construction above described with the door opening and shelf at the specific angles mentioned has been found to give the best results both for the maximum and minimum quantities, thereby resulting in a very efficient churn and butter worker for certain sizes of devices, particularly the smaller sized device of this class.
